Title: Conditional yield to hypervisor instruction
Inventor: William James Deacon
IPC: G06F9/48
Filed: 2019-02-28
Abstract: A processor has a conditional yield to hypervisor instruction. When the processor executes the instruction, it determines if a condition is satisfied. If it is satisfied, the executing virtual machine is suspended and control is transferred to the hypervisor. Information about the condition is transferred to the hypervisor to help determine when to reschedule the virtual machine. The information may be stored in a hypervisor trap control register. A trap control indicator may be set to indicate that there is valid information in the trap control register. The instruction may be a wait for event instruction. In this case, the condition is satisfied if the event has not happened. The event may be an access to a memory address tracked by an exclusive access monitor. If the address is a virtual address, this may be translated to a physical address.

Filed: 2020-12-22
Abstract: A mobile apparatus (e.g. personal device) is downloading and updating a thematic map with data from a remote database server using a location sensor (e.g. GPS). The apparatus is then presenting to a user the thematic map with suggested activity options in a first display mode. The user then selects an activity based on: a user preference, activity history, activity intensity, time, date, location or adjacent location. The apparatus then starts the selected activity and displays performance related information in the first display mode (e.g. relating to position, distance, speed, heart rate). The apparatus then enters a second display mode (first power save mode) and displays time and an activity thematic map with reduced functionality (e.g. reduced display resolution, colours, content, slower updates). Then the apparatus is entering a second power save mode by putting a processing core in hibernating mode. Finally the apparatus enters a third display mode whereby a system clock updates the display showing a static thematic map and time/date. The apparatus may have high power and low power processing cores each one controlling a respective display mode. The activity options may include updated heatmaps created for different sports in the said location.

Title: Method for detecting comparable persons to a search person, surveillance system, in particular for implementing the method, as well as a computer programme
Inventor: HOLGER BEHRENS
IPC: G08B13/196
Filed: 2021-05-17
Abstract: A method and apparatus for ambiguously identifying two or more potential matches to a search target. A plurality of classification people 3 in a classification image 2 are classified by extracting values W1,W2,W3 for classification characteristics K1,K2,K3. These values are compared with values extracted from the search image (5, fig.2) to identify at least two potential matches (7, fig.2) for the search person (4, fig. 2). The classification is ambiguous so that the system does not handle data allowing any specific person to be uniquely identified. Ambiguity may be achieved by using a classification image that is lower quality than the maximum available image quality, or by limiting the number of classification characteristics used to identify people. The method may be used to satisfy General Data Protection Regulations that prohibit the handling of biometric data, without consent, that allows an individual to be uniquely identified. A trajectory for each classification person may be generated from the classification images and used to create a probability graph of trajectories. The classification images may be captured by one or more surveillance cameras 1.

IPC: H04N9/31
Filed: 2019-07-02
Abstract: A projector has a liquid crystal spatial light modulator (SLM) 903 where each pixel has a director rotating in a plane to display a pattern. The SLM is illuminated by polarised light 907 from a light source and is spatially modulated by a hologram to form the light pattern. The polarised light is structured light which forms a plurality of light spots 905a each illuminating a respective array pixel 903a. The angle of incidence of the light on the array of pixels is greater than zero. Each pixel is rectangular with a length to width aspect ratio so that received light does not crossover into another pixel due to the angle of incidence. The pixel length is parallel to the plane of incidence of the polarised light and the pixel’s width is perpendicular to its length. The light source may form structured light using a spot-generating hologram, a diffractive optic element (DOE) or a microlenslet array 901. The size of each light spot may be less than the pixel size such as < 90%, < 85% or < 80% of the pixel size. The length to width aspect ratio of each pixel may be in the range 2:1 to 5:1.
